ABSTRACT:
A fingerprint area and a barycentric position of the area are obtained for a current sensor image, and an area near the barycentric position is divided into a plurality of small blocks. An image area that agrees with a fingerprint image is searched for, for each of the small blocks with respect to the fingerprint area in a previous sensor image. A candidate vector is obtained from a deviation between the position of the small block in the current sensor image and the position of the image area in the previous sensor image corresponding to the small block. A candidate vector with the highest matching degree between the fingerprint images in the current and previous sensor images is selected from the candidate vectors to obtain a detected vector, and the detected vector is corrected to exclude an influence of erroneous detection and to control a movement of a pointer.
